Abstract
The experiment of this study uses the mold with microns (5 um) and sub-micron (0.5 um) pattern-size to imprint on the conjugated polymer, MEH-PPV and P3HT, and the mold of patterns will reproduce onto the film surface of the conjugated polymer. There are several aspects in this study. First, we observe the deformation situation of the imprinted polymer film. And then, we discuss the factors that influence on Photoluminescence (PL) of conjugated polymer after imprinting which caused by the mold size and shape, concentration of the conjugated polymer, initial film thickness, temperature during imprinting, substrate effect, imprinting time and the strength of stress, respectively. Finally, we try to explain the result of the imprinting data by stress relaxation after imprinting and the crystallization of conjugated polymer.
